No one knows.
We can measure space distance in light years (distance light travels in a year, at 186,000 miles a second or 300,000 km/s). One light year is nearly 10 trillion km.
Current best estimates suggest the universe has an age of about 13.7 billion years. At the very beginning, just after the big bang, it briefly but dramatically expanded at a rate far faster than the speed of light (known as the period of inflation) and then at a lesser speed since then. This has placed much of the universe so far away that it can never now be reached if travelling at the speed of light.
We can see 'back' to some distant objects as they appeared about 13 billion years ago (and theoretically we could see back to just after the big bang 13.7 billion years ago). The calculations for their current distance (and thus the radius of the visibleuniverse) are complicated by the fact that the space has been expanding in the meantime, but it must exceed (the speed of light) x (the time taken to get here), i.e. over 13 billion light years [or 130 billion trillion kilometers]. Taking interim expansion into account multiplies this figure by about three times, and also gives the radius of the observable universe - the bits we can see assuming we can see back to just after the big bang - as 46.5 billion light-years.
But, how big is the universe including the non-observable portion, the bit we have permanently lost track of because of inflation? The answer has been estimated as at least 1023 times as large, that's 100,000,000,000,000,000,000,000 times as large, and possibly far, far larger than that.

no they do not
How long would a jumbo take to travel to the sun?
It takes about 3 days to get to space. No one can go to the sun it is to hot.
Anubis fly to space?
As long as I know, he didn't fly to space
Can you see the Nile from space?
Yes, the Nile River is visible from space due to its size and the contrast it creates with the surrounding landscape. Its long, winding shape can be easily seen from satellites and spacecraft orbiting the Earth.

How long does it take a rocket to go to space?
The space shuttle went from sea level to orbit in about 8 minutes
Space center Pokemon Emerald?
if you wait a long time you can go to the space center and go to the guy next to the window he will ask if you want to go to space then say yes and you have one chance of catching deoxys on the moon
What is the highest a rocket can go?
How long is a bit of string? and how deep is space? there is no real answer.
How long would space take to go through?
space is infinite, as far as we know. you would just keep going
What is the difference between space stations and space shuttles?
A space shuttle is the ship in which theastronauts use to get to the space station The space station is where the astronauts typically go to refuel and to stay when they r on a long mission.
